This is the SDK for building custom firmware for the RP2040 on the pico-ice board and RP2350 on pico2-ice board.

Provided you have the compilers setup. For riscv, you may add -DPICO_GCC_TRIPLE=riscv64-unknown-elf to the cmake command if your 'riscv64' compiler supports rp2350/rv32.

• clone the repository
• run git submodules update --init
• got into the folder of the example you wish to try
• mkdir build && cd build
• cmake -DPICO_BOARD=pico_ice .. or cmake -DPICO_BOARD=pico2_ice .. or cmake -DPICO_BOARD=pico2_ice -DPICO_PLATFORM=rp2350-riscv ..
• make -j8
• Copy the generated uf2 to the board after setting it to flashing mode
